A shock tube connector system comprises a substantially cylindrical det-onator (B) having a longitudinal axis (15), a block body (A) receiving the det-onator (B) therein, and an end cap (C). The detonator (A) includes an axisym-metric exterior shell including a cylin-drical main section (10), a cylindrical explosive end portion (12) having a diameter less than the diameter of the main section (10), and a transition portion (14) connecting the main section (10) and the explosive end portion (12) of the shell. An explosive charge is con-tained within the explosive end portion (12) of the shell and is distributed along the longitudinal length of the explosive end portion (12). The explosive charge preferable comprises two portions (62A, 62B) of lead azide or a first charge portion (72A, 74) of lead azide and PETN and a second charge portion (72B) of PETN. An initiating shock tube (16) is operatively connected to the explosiv e charge via a delay element (65, 75). The block body (A) includes a housing (20) within which the main section (10) of the detonator (B) is received. A tube holder (30) connected to one end (27) of the housing (20) includes a base member (32) having a bore within which the explosive end portion (12) of the detonator (B) is received. The tube holder (30) is T-shaped and includes a pair of engaging flanges (36) spaced from the base member (32) on laterally opposite sides of the base member (32) to define therebetween pair of engagi ng slots (38) extending parallel to the longitudinal axis (15) of the detonator (B) and alongside the explosive end (12) of the detonator ( B) received in the bore. Each engaging slot (38) is adapted to frictionally grip at least four shock tubes (D) alongside the explosive end (12) of the detonator (B) with the longitudinal axes of the shock tubes (D) substantially orthogonal to the longitudinal axis (15) of the detonator (B). The end cap (C) is connected to the other end of the housing (20) and secures the detonator (B) within the block body (A).</SDOAB >
